HDR with GIMP Tutorial

A tutorial on making High Dynamic Range photos using the GIMP HDR or similar software.

GIMP HDR consist of many part you should know such as GIMP HDR plugin , GIMP HDR script, GIMP HDR Effects, all you can find in GIMP HDR Tutorial. If you do not know what High Dynamic Range (HDR) is or how it works, read on this HDR with GIMP articles.

On this HDR with GIMP articles which is intended for a wide range of people, what can happen to bits for you with the following information. I apologize for the level of detail in the main instructions, but I think you can skip the parts that I see, and can also put in the detail for people who do not.

HDR with GIMP is very easy, If you are comfortable with the concept of HDI and want to know how it is done in photo editing software, go to step 3
If you are familiar with the process of HDR imaging and just want more information on how to do it in GIMP, go to step 4
If you are familiar with the GIMP interface and just want a quick installation instructions on how to make HDR (for example, if the theory is bored and you want to do some HDR images), go to the wrap-up stage in step 10 . The details of each step are in. .. the appropriate step.

If you know the theory , how to make HDR images and are familiar using HDR with GIMP .. I'm not sure why you're reading this, but hello anyway. My attempts unfortunate (I am relatively new to HDR and GIMP) are in the later stages, maybe you could give me some advice? : D

Finally, if you find this instructable useful (or even especially) and have constructive suggestions for how you can improve, let me know and I'll edit.

So, what is dynamic range?

You know ,a camera, like the human eye, has a light sensor that captures the image. The sensor has a limited sensitivity to light, so under any circumstances because there is a wide range of light levels that the camera can distinguish. Whether you are looking for the sun or two suns, the camera electronics will throw in the towel bit and say "this is white." Similarly, unless there is a camera flash or very night vision, looking for a dark gray bat in some slightly darker gray around at night, the camera says "it's black." The difference in the level of light in the darkest levels of the camera can distinguish between the lightest and can be distinguished is called the dynamic range for normal digital camera, is 100 to 1, the human eye is the range of
